SpreadView: A Multi-touch Based Multiple Contents Visualization Method Composed of Aligned Layers

Abstract

There have been many studies concerning development of large scalable interactive displays employing multi-touch interfaces, which is rapidly replacing conventional static methods of presenting information to the public. Interactive large displays are used in various fields, such as in the education sector as interactive whiteboards, way-finding screens in retail and hospital environments and so on. We propose the SpreadView, a new method for displaying digital contents on public large display, which generates pages corresponding to the traditional content files included in the traditional folder in PC, and generates an information display layer including a folder display portion corresponding to the traditional folder and giving output the aligned information display layers. The SpreadView senses multi-touch events to change an output format of the information display layer according to various user manipulation patterns such as one point touch or one point drag on a page, two point touches or pinch on a page, multiple touches on multiple pages in the information. Through these various touch manipulations the SpreadView rearrange information display so as to correspond the user's expectations. The SpreadView may provide a design motivation to improve the usability in manipulating big amount of digital contents under the other forms of computing environment such as tabletop computing, virtual reality and augmented reality.
